Abstract

L'invention concerne un procédé servant à défibrer un matériau contenant des fibres dans un dispositif fonctionnant selon le principe d'un malaxeur à broches périphériques. Ce dispositif comprend un carter contenant un premier rotor (11) pourvu de surfaces de collision; un deuxième rotor (12) concentrique par rapport au premier rotor, pourvu de surfaces de collision et conçu pour tourner dans un sens opposé par rapport au premier rotor ou un stator concentrique par rapport au premier rotor et pourvu de surfaces de collision. Ce dispositif comprend, de plus, un orifice d'alimentation (14) situé dans le carter et s'ouvrant sur le centre des rotors (11, 12) ou du rotor et du stator, ainsi qu'un orifice d'évacuation (15) situé dans la paroi du carter et s'ouvrant sur la circonférence du stator ou du rotor situé le plus à l'extérieur. On introduit le matériau contenant des fibres dans l'orifice d'alimentation (14) vers le carter et on le fait s'écouler avec de l'air ou du liquide, ce qui génère une suspension à travers les surfaces de collision des rotors emboîtés (11, 12) ou du rotor et du stator emboîtés vers l'orifice d'évacuation (15) à travers lequel ladite suspension est évacuée du carter. L'invention concerne également le dispositif servant à mettre ce procédé en application.
